I pitched the yeast way to early. I had a few beers today and its been sitting in a jar for 30 min has another 15 min till my wort cools. Will this cause serious problems or should i crack another beer?

In my experience, staters just give you a quicker ferm start. If you get healthy yeast in a well oxigenated wort you well get a strong fermintation. The yeast is male in nature and wants to be fruitful and multiply. You have do something very wrong to stop it.
